java - 所有 gms/firebase 库必须使用完全相同的版本。找到版本 15.1.0、15.0.2、15.0.1、15.0.0。

Question

尝试在我的项目中实现 Firebase。

Gradle 文件:

apply plugin: 'com.android.application'

android {
compileSdkVersion 27
defaultConfig {
    applicationId "com.ghaleh.myapplication"
    minSdkVersion 16
    targetSdkVersion 27
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
     }


buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support:support-media-compat:27.1.1'
implementation 'com.android.support:support-v4:27.1.1'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-  core:3.0.2'
implementation 'com.google.firebase:firebase-messaging:15.0.2'
}
apply plugin: 'com.google.gms.google-services'

我收到这个错误:

All gms/firebase libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 15.1.0, 15.0.2, 15.0.1, 15.0.0. Examples include com.google.firebase:firebase-iid:15.1.0 and com.google.android.gms:play-services-measurement-base:15.0.2

根据 Google's Maven Repository firebase-messaging 的最新版本是 15.0.2，我收到了 firebase-iid:15.1.0 的错误所以我无法将 firebase-messaging 升级到更高版本或实现 firebase-iid:15.1.0 以匹配版本。

我已经尝试过此处推荐的其他解决方案:1 , 2 , 3但没有一个有用。

我也试过这个(但它似乎不是一个合适的解决方案):

implementation ('com.google.firebase:firebase-messaging:15.0.2') {
    exclude group: "com.google.android.gms"
}

我得到这个错误:

Error:Execution failed for task ':app:transformDexArchiveWithExternalLibsDexMergerForBazaarDebug'.
java.lang.RuntimeException: com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex

提前致谢。

您需要更新 google-service 插件才能使用:

classpath 'com.google.gms:google-services:3.3.0'

为了能够避免这些错误，还要升级到android studio 3.1

If you're not using Android Studio 3.1 to develop your app, you will need to upgrade in order to get the correct version checking behavior within the IDE.
